Blind and ultimately controlled by the Tyranid synapse-creatures they protect, these half-sentient but ferocious creatures appear to have been bio-engineered specifically to counter anti-Tyranid doctrine. It is also believed that Space Marine DNA was incorporated into the creation of the first Tyrant Guards, explaining this biomorph's extreme resilience in combat.
The Tyrant Guard withdraws into its protective carapace, disabling it while changing armor type from super heavy infantry to vehicle and increasing health regeneration by 15 hp/s.
The Tyrant Guard stampedes to the targeted location, increasing its speed by 100%. Each second, all units in radius 4.5 take 20 power melee damage and ability knockback. Targets in radius 3 take an additional 20 power melee damage. Damage can only be dealt to each individual model 2 times every 2.5 seconds. 80 second cooldown.
